Marisa’s car accelerates at an average rate of 2.6m/s^2. Calculate how long it takes her car to accelerate from 24.6m/s to 26.8m
djverab [1.8K]

given info is... Acceleration(a)=2.6m/s^2

                       final velocity(v)=26.8m/s

                       initial velocity(u)=24.6m/s

need to find.... time(t)=?

a=\frac{v-u}{t} \\2.6=\frac{26.8-24.6}{t} \\\\

t=\frac{v-u}{a}

t=\frac{26.8-24.6}{2.6}

t=0.846s

For each of the following decays or reactions, name at least. one conservation law that prevents it from occurring.(c) p → π⁺ +
Amanda [17]

(c)p→π⁺₊π⁺₊π

Baryon number is +1 on the left side of the equation, 0 on the

right side. Baryon number is not conserved.

<h3>How do you determine whether a baryon number is conserved?</h3>

  • According to the law of conservation of baryon number, the sum of the baryon numbers of all incoming particles equals the sum of the baryon numbers of all particles produced by the reaction. Energy, and so on, are conserved even if the incoming proton has sufficient energy and charge.
<h3>What is Baryon Number</h3>
  • In particle physics, the baryon number denotes which particles are baryons and which particles are not. Each baryon has a baryon number of 1, and each antibaryon has a baryon number of -1. Other non-baryonic particles have a baryon number of 0. Since there are exotic hadrons like pentaquarks and tetraquarks, there is a general definition of baryon number as:
  • B=1/3(n_{q} -n_q^{-} })
  • wheren_{q} represents the number of quarks and nq represents the number of antiquarks.

Which of the following statements about Ohm's Law is true? A. Increasing the voltage decreases current. B. Keeping the same volt
Luden [163]

The correct answer is option D

The Ohm's Law states that current passing through a conductor is directly proportional to the voltage across the conductor.

Current =voltage/ resistance

The resistance causes hindrance in the path of the current and does not allows it to flow so, we must reduce the resistance to increase the flow of current in the conducting wire.

h(t) = - 16t2 + 64t + 112 where t is the time in seconds. After how many seconds does the arrow reach it maximum height? Round t
laila [671]

Answer:

2 seconds

Explanation:

The function of height is given in form of time. For maximum height, we need to use the concept of maxima and minima of differentiation.

h(t)=-16t^{2}+64t+112

Differentiate with respect to t on both the sides, we get

\frac{dh}{dt}=-32t+64

For maxima and minima, put the value of dh / dt is equal to zero. we get

- 32 t + 64 = 0

t = 2 second

Thus, the arrow reaches at maximum height after 2 seconds.
